Adds the ability to put localized strings in `StripeCore` and sets up infrastructure for any new module to contain localized strings. Now each module will have...
- Its own version of `STPLocalizedString`
- Its own set of `Resources/Localizations/*.lproj/Localizable.strings` files
* Adds new scripts to push new localized strings to lokalise, pull translations from lokalise, detect missing translations, and detect newly added localized strings
* Better git diff detection.
* Use custom final status
* Remove custom lang map (set in lokalise instead).
* Request zh-Hant
* Better newline handling
